Fodor's Expert Review Dinosaur National Monument

Straddling the Colorado–Utah border, Dinosaur National Monument is a must for any dinosaur enthusiast. A two-story hill teeming with fossils—many still in the complete skeletal shapes of the dinosaurs—greets visitors at one of the few places in the world where you can touch a dinosaur bone still embedded in the earth. The Colorado side of the park offers some of the best hiking in the West, along the Harpers Corner and Echo Park Drive routes and the ominous-sounding Canyon of Lodore (where the Green River rapids buffet rafts). The drive is accessible only in summer—even then, four-wheel drive is preferable—and some of the most breathtaking overlooks are well off the beaten path.
